My truck will start and runs fine, but if I shut it down, it won't restart unless I either wait about 20 minutes, or spray gasoline into the throttle body, then it starts back up fine. It cranks and tries to turn over, but will not start. My EGR valve I know is bad since the check engine light is on and I had the code read by AutoZone. I just haven't replaced it yet. I don't know if that has anything to do with it or not. Thanks for your help!

Had similar problem on my 5.0 '96 F-150. Turned out to be the fuel inertia switch. It appears to have tried to trip for whatever reason, but crud buildup around the button was preventing it, so sometimes it would lose connection, and the truck would just shut off. Usually it would start back up in an hour or 2.I replaced the crank sensor, ICM, front fuel pump(had a bad check valve anyway)and a relay to no avail. Went through Chilton diagram and found that switch, figured it was worth checking out. Fiddled with it, cleaned it, tripped it in and out a few times, truck started and haven't had a problem since.
